Connecting VisualVM to Oracle JVM
Has anyone had any success connection to the database JVM using Visual VM.
I've started the jmx agent using dbms_java.start_jmx_agent, and am able to connect with jconsole without problems, but when I try to connect with VisualVM, I get an error message java.lang.NumberFormatException: For input string: "(PID=5044;SID=248)"
I've taken a look at the VisualVM code and the problem appears to be that when VisualVM reads the virtual machine name, it gets something like (PID=X;SID=Y)@SERVERNAME. Visual VM then takes everything before the @ in that name string and attempts to convert it to an integer.
Versions:
Oracle Database 11gR2 running on Windows.
Oracle VisualVM 1.3.2
For background, I'm trying to profile a Java procedure which is running much slower inside the DB than outside of it.
A quick fix might be to 'rename' the java virtual machine for the database session in question, but I can't find a way to do that? Any ideas?
Many thanks,
James
I never solved this. but did find a very crude workaround. Here it is in case anyone has a similar problem .
The reason I needed visualVM was to profile some slow running code within the DB. The best I could do in the end was to use jconsole and repeatedly use the EmitStackTrace mbean option. Using this it is possible to build a picture of which methods the JVM is spending most of its time in.
The problem by the way was that one method was not being compiled by the JIT compiler, so it was always being interpreted. Fortunately that method wasn't essential to the process and by avoiding it, performance improved to the same, (actually very slightly faster) than the standard JVM /JRE.

1) I have visualvm *32 install

TRXHi,
as you can see, you are running VisualVM on 32bit JVM
1.6.0_20; Java HotSpot(TM) Client VM (16.3-b01, mixed mode, sharing)
You don't need to unistall 32bit JVM. Just tell VisualVM to use tour 64bit JVM.
One way is to use --jdkhome command-line switch.
visualvm_13\bin\visualvm.exe --jdkhome <path_to_64bit_JVM>
If you want to change it permanently, you can edit
visualvm_13\etc\visualvm.conf
uncomment and edit netbeans_jdkhome entry to point to your 64bit JVM.

Java multithreading support in Oracle JVM
Dear all,
I have some questions and observations regarding multithreading support in Oracle JVM. I have some java code that is stored in the database and is multithreaded (in separate threads I run a plsql procedure that does a lot of precessing). If I run the code with my standalone JVM it works like a charm, everything gets executed in separate threads. But if I store the code in the database and run it (with the custom JVM Oracle implemented for the server) it does not do any threading, all I have is a single thread that runs everything sequentially.
The logic is this: using JDBC I create a connection, get a parameter (number of threads) and then launch the threads (each thread creates its own connection and runs the plsql procedure). No resource is shared (I have no synchronized code, I do not yield).
My question is: does Oracle JVM supports multithreading or not? If yes, how to achieve it? Maybe there is something handled in JDBC? (although my code useses JDBC is not multithreaded) If this is not possible with java, do you now how to run something (oracle function, procedure) concurrently with PLSQL? (I tried with DBMS_JOBS but it does not work on all my databases and our DBAs discourage the use of them). Performing multithreading my launching different sqlPlus processes is not an option (as we have no security standard regarding the authentication -> connection is made by specifying in clear text the user and password).
I wanted to use java because is more simple, secure (the connection is already established as the classes are stored in the database) and easy to maintain (until now we use different scripts which run on Unix and Windows and this leads to double work).
The Oracle versions I use are 10g and 11g.
Thank you all very much for your time
Just the best,

(Obviously the other post answers your question.)
If I am reading that correctly then you have a management issue - not a technological one.
You have a task to complete, presumably doing it efficiently is something that the company wants.
And you have two alternatives both of which the DBAs are not allowing you to use.
So at that point it is up to management to insist that the DBAs provide specific technological reasons (not hand waving) why those solutions are not suitable. And they should also be required to provide the outline of an alternative that is suitable.
Besides that you might consider why your solution cannot be implemented entirely in a single threaded PL/SQL routine. The fact that is harder is not a reason when the point of the excercise is to create something that is more efficient. -
Increase Scope of Custom variables in Oracle JVM
We on our project are facing the following problem, any suggestions to work around this would be appreciated :
We our using Oracle 9i JVM for development
Our Sample problem flow is as follows :
A package PKG1 has three procedures PROC1/PROC2/PROC3
A java class JC1 is invoked by a procedure PROC1 - JC1 is running under oracle JVM.
JC1 does the task of mapping a custom user defined java object to an oracle collection and invokes a procedure PROC2 (we are using thin client connection object in JAVA by means of simple JDBC calls to connect to the database.) which takes the oracle collection as input parameter and does processing over it.
A procedure PROC3 does the task of calling PROC1 and then tries to access global variables defined in the package set by PROC2 , which comes out as a failed operation throwing the error as:
ORA-06531: Reference to uninitialized collection
The reason for the above behavior is : In the parent oracle session invoked by PROC1 the class JC1 opens another child database session for PROC2 and thus values set in the child thread are not visible to the parent.
Required support: Is there a means for setting up of some property in ORACLE or Java which can enforce the JAVA CLASS to use its parent / invoking oracle session or if there is any other approach to overcome the above situation.Anand,
I believe the Java in the Oracle Database forum is more appropriate for your question.
You said:
The reason for the above behavior is the parent oracle session opens
another child database session
How do you do this? And why? And what evidence makes you certain that this is the problem?
Good Luck,

JDBC connection error to ORACLE in JSP
To connect to the Oracle database (using java server pages), we have installed the oracle client on web server box during the installation, it has installed jdbc classes also. We have put this classes in the Environment variable - path and class path. We have also put the same in class path of JVM (virtual server -> java tab -> configure jvm attributes) also. Still the connectivity with database is not getting established!!

Oracle Team?? EJBean Problem on Oracle JVM
Hi,
I am using Jdeveloper3.1 and Oracle8.1.6 for my application. I could deploy and run the EJB on Oracle JVM without any problems. But when I am trying to connect to the Database it is giving me the null value instead of 'Y' or 'N'. The same EJbean I used as the USEBEAN in JSP and it is giving me correct results.

Can you please tell me the problem. I have wasted 2 days on this.

nullYou're running this EJB in iAS, right?
You have to grant JAVAUSERPRIV to the user running your EJBs so that it is allowed to open a JDBC Thin socket out of the JVM to the backend database.

Need to connect to upgraded Oracle EBS R12 version from R11. The current ODI set up is pointing to R11, Can i use the same connection to point to R12? Please hele experts...
Rp1. in physical connections part can i use the same work schema
2. Can i use same contexts created or do i need to create everything as new and then try?
Thanks,
Rp.
Hi,
As you mentioned that you just upgraded the database, so the data is same and schema is same you can connect with the same work schema.
Yes, you can use the same contexts , but need to do Reverse Engineering for your new database.
And about data server, i think you also have no need to create new data server, if hostname,sid and port etc are same as these were with R11(consult with your DBAs regarding it) -

How do I avoid re-entrant problems in Oracle JVM
I have a Java program called LanguageFunctions. This Java program has several methods that translate the data within a String or CLOB. I want to use this Java program as a stored procedure, and specifically the methods as Oracle functions. I want this function to be accessed simultaneously without either re-entrant, lock or performance concerns. I want to be able to use the functions something like this:
SELECT TO_CHINESE(VARCHARCOL1) FROM DUAL;
SELECT TO_FINISH(CLOBCOL1) FROM DUAL;
I am having trouble understanding the Java requirements for these methods. I am greatly concerned about multi-user usage and issues with re-entrant code. Does this have to be a static class? If not, how when and where does it get instantiated (I hope not for every invocation of the function)? How to I avoid having one user accidentally changing the data within the method when executed in parallel?
BTW: I have successfully moved these into the Oracle JVM, and executed them as a single user. My main concern is the re-entrant code issues.
ThanksThanks for the reply, I meant no disrespect, I was just trying to be a little funny...
I did read that any method that you want to use as an Oracle function must be static. So I understand that as a given. However, the class I am converting uses static Class variables. You can see this in the example as the textOut variable.
When two users are accessing this function in parallel, I could see the following series of events ocurring, and it is my concern. There is only one textOut, and I believe it can be modifed by both functions simultanesouly with unexpected results. I'm assuming my for loop is set to x < 2.
SessionA issues: SELECT TO_DANISH('HELLO') FROM DUAL;
A --> textOut = ""
A --> textOut = "HELLO"
A --> textOut = "HELLOxy"
A --> textOut = "HELLOxyxy"
SessionB issues: SELECT TO_DANISH('GOODBYE') FROM DUAL;
B --> textOut = ""
A --> textOut = "xy"
B --> textOut = "GOODBYE"
A --> textOut = "GOODBYExy"
Session A returns: "GOODBYExy" (expected "HELLOxyxy")
B --> textOut = "GOODBYExyxy"
B --> textOut = "GOODBYExyxyxy"
Session B returns: "GOODBYExyxyxy" (expected "GOODBYExyxy")I'm I correct in my assumption that this is an issue? If so, what type of programm architecture would be best to use to manage this? I've tried to provide a simple working example of the issue, but the program that I'm working on actually alters the contents of textOut (as a static Class variable) in 5 or 6 different methods, including one method using recursion. I know I may need to make changes to the program architecture to make it work properly in a multi-user environment as an Oracle function. I'm just a little confused on what the appropriate architecture is. Once again any help is appreciated!

Connecting to an Oracle database after clicking on a foi
Does anyone know how or have any examples on how to connect to an oracle database after clicking on a 'feature of interest' in MapViewer? I want to be able to click on a 'feature of interest' on the map, and have a list of records from an oracle table displayed using the identified key of the foi. I am able to create the feature of interest, and add the event listener for 'mouse click', but am unsure how to connect to the database at this point. I have been able to connect to the database in a different jsp, but not from here. Thank you.
1. Create a JSP page that does the database query. It should take the foi id as an input parameter.
2. In the foi mouse click listener, display the JSP page in iframe. The iframe can be placed outside the map or inside the info window. The function should do something like this.
function myClickListener(point, foi)
mapview.displayInfoWindow(point, "<iframe id='my_iframe_id' frameborder=0 width=300px height=400px />", 300, 400) ;
var myIframe = document.getElementById("my_iframe_id") ;
myIframe.src = "http://myhost/myjsp?key=" + foi.id ;

Fails to connect to the Oracle yum public server
Hello,
I would like to connect to the Oracle public yum server so I can install packages from the Oracle Linux via a yum client for my RHEL 5.4
I am trying to download and copy the appropriate yum configuration file in place, by running the following commands as root:
Oracle Linux 5
# cd /etc/yum.repos.d
# wget http://public-yum.oracle.com/public-yum-el5.repo
--2011-10-29 15:53:41-- http://public-yum.oracle.com/public-yum-el5.repo
Resolving public-yum.oracle.com... 141.146.44.34
Connecting to public-yum.oracle.com|141.146.44.34|:80... failed: Connection timed out.
Retrying.
It disabled the Linux firewall by /etc/init.d/iptables stop but it still doesn't help.
Thank you.feverlove wrote:

Connecting to public-yum.oracle.com|141.146.44.34|:80... failed: Connection timed out.This has nothing to do with the firewall (which only blocking incoming traffic, not outgoing traffic by default) and all to do with your routing. You have DNS properly configured, but you need to double-check your default gateway and other settings to make sure you can connect to a server on the internet directly. If you need to use a proxy server to make connections, you will have to configure that as well. -
Are there any known issues around file read/write in Oracle JVM. I finally got around the issue of getting the error that says no permission is there by giving <<ALL FILES>> option, but still I don't see a file being created. Any help is appreciated.
Code:
try{
fwriter = new PrintWriter(new FileOutputStream("debugLog.txt",true));
} catch (IOException ioe) {
System.err.println("IO Exception for Output File" + ioe.getMessage());
Thanks.
-MujibA couple of suggestions:
1. (Please don't be offended...) I assume you have some stuff like:
fwriter.println("hello");
fwriter.flush();
fwriter.close();
in your try block?
2. Try catching FileNotFoundException and SecurityException also.
3. Try providing a full path on the file just to make sure it's not buried somewhere odd.

Test program으로 JVM test해보기
Java Stored Procedure 만들기
다음과 같은 순서로 Java Stored Procedure를 만들어 봅니다.
1. Java program을 만듭니다.
2. program을 database로 loading합니다.
3. Java program을 SQL (PL/SQL Wrapper)로 publish합니다.
4. SQL 또는 PL/SQL에서 만든 Java program을 호출합니다.
Step 1: Java program을 만듭니다.
======
EchoInput.java
public class EchoInput {
public static void main (String[] args){
for (int i=0; i<args.length;i++)
System.out.println(args);}}
Step 2: program을 database로 loading합니다.
======
UNIX prompt상에서 다음을 실행합니다:
% loadjava -u scott/tiger -v -r EchoInput.java
또는 SQL*Plus에서는 다음과 같이 할 수도 있습니다:
CREATE OR REPLACE JAVA SOURCE NAMED "EchoInput" AS
public class EchoInput { public static void main (String[] args) {
for (int i=0; i<args.length;i++) System.out.println(args[i]);}}
Step 3: Java program을 SQL (PL/SQL Wrapper)로 publish합니다.
======
SQL 또는 PL/SQL에서 만든 Java program을 호출하기 위해서는
Java program을 SQL (PL/SQL Wrapper)로 publish해야 합니다.
이과정을 PL/SQL Wrapper를 만든다고도 합니다.
일단 published/wrapped가 되면 SQL 또는 PL/SQL을 통해 호출될 수
있습니다.
예제 :
create or replace procedure echo_input (
s1 varchar2, s2 varchar2, s3 varchar2)
as language Java
name 'EchoInput.main(java.lang.String[])';
Step 4: SQL 또는 PL/SQL에서 만든 Java program을 호출합니다.
======
call dbms_java.set_output(5000);
call echo_input('It', 'works', 'now!');
주의 : SQL*Plus에서 실행할 경우 먼저 'set serveroutput on'을
해주시기 바랍니다.
결과 화면
SQL> set serveroutput on
SQL> call dbms_java.set_output(5000);
Call completed.
SQL> call echo_input('It', 'works', 'now!');
It
works
now!
Call completed.

2. program을 database로 loading합니다.
3. Java program을 SQL (PL/SQL Wrapper)로 publish합니다.
4. SQL 또는 PL/SQL에서 만든 Java program을 호출합니다.
Step 1: Java program을 만듭니다.
======
EchoInput.java
public class EchoInput {
public static void main (String[] args){
for (int i=0; i<args.length;i++)
System.out.println(args);}}
Step 2: program을 database로 loading합니다.
======
UNIX prompt상에서 다음을 실행합니다:
% loadjava -u scott/tiger -v -r EchoInput.java
또는 SQL*Plus에서는 다음과 같이 할 수도 있습니다:
CREATE OR REPLACE JAVA SOURCE NAMED "EchoInput" AS
public class EchoInput { public static void main (String[] args) {
for (int i=0; i<args.length;i++) System.out.println(args[i]);}}
Step 3: Java program을 SQL (PL/SQL Wrapper)로 publish합니다.
======
SQL 또는 PL/SQL에서 만든 Java program을 호출하기 위해서는
Java program을 SQL (PL/SQL Wrapper)로 publish해야 합니다.
이과정을 PL/SQL Wrapper를 만든다고도 합니다.
일단 published/wrapped가 되면 SQL 또는 PL/SQL을 통해 호출될 수
있습니다.
예제 :
create or replace procedure echo_input (
s1 varchar2, s2 varchar2, s3 varchar2)
as language Java
name 'EchoInput.main(java.lang.String[])';
Step 4: SQL 또는 PL/SQL에서 만든 Java program을 호출합니다.
======
call dbms_java.set_output(5000);
call echo_input('It', 'works', 'now!');
주의 : SQL*Plus에서 실행할 경우 먼저 'set serveroutput on'을
해주시기 바랍니다.
결과 화면
SQL> set serveroutput on
SQL> call dbms_java.set_output(5000);
Call completed.
SQL> call echo_input('It', 'works', 'now!');
It
works
now!
Call completed.
SQL>

First of all, I think your dot... button is broken, it keeps repeating which makes it SO much harder to read your post.
Secondly, I suggest you take your question to the Netbeans mailing lists. This is a Java programming forum, not a technical support forum for the hundreds of tools available to support Java programming.
